May 29, 1986

An item in the Business Ticker column of the May 27 Tribune reported incorrectly that the price of a seat on the Chicago Mercantile Exchange reached an all-time high of $98,000 as of May 21. That price was a record for a seat on the Index and Options Market, one of three divisions of the Merc. The highest prices paid for seats on the other two divisions, according to a spokesman, are $175,000 for a seat on the full Merc on May 20, and $161,000 for a seat on the International Monetary Market on May 22. The Tribune regrets the error.
